Troubleshooting Windows Update Issues with Vista

April 21, 2008 – 6:10 PM

If you are having problems getting certain updates installed on Vista, there are two places you can look to troubleshoot:

%windir%\windowsupdate.log, a log file for Windows Update events

%windir%\Logs\CBS\CBS.log, a log file that tracks events to the servicing stack

These log files include the following fields: Time/Date Stamp, Message Severity, Message Source, Operation Type, and Main Text.
